IMPROVEMENT IN LOCKS.

Specification forming part of Letters Patent N0. 58,898, dated October 16, 1866.

.To all whom it may concern:

Be it known that I, WILLIAM SnLLEns, of the city, count-y, and State of New York, have invented a new and Improved Lock; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the aecompanying drawings, forming part of this speciication, in Which- Figure 1 is an interior view of my improved lock; Fig. 2, a vertiealfsectionof the same, taken in the line wr, Fig. 1 Fig. 3l a top view ot' the same; Fig. 4, an interior view of my improvement, a modification of that shown in Fig. 1; Fig. 5, a vertical section et' Fig. 4, taken in the line y y; Fig. 6, a top view ofthe same.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and improved lock of that class which are designed for articles having hinged or rising-and-falling lids, covers, or tops-such, for instance, as pianofortes, sewing-machine, cases, Ste.

The object of the invention is to obtain a lock of the class speeied which will have its bolt operate with a single movement, or a movementin one direction only, and be simple in construction and capable of being manufactured at a moderate cost.

A, Figs. 1 and 2, represents the case of the lock, which may he of any suitable form, and B is the bolt, of segment form, and cast or otherwise made with ahub or boss, a, at each side to fit into holes in the side of the loekcase, saidllubs or bosses forming journals for the bolt to turn upon, and having a hole passing entirely through them, of rectangular form, to receive the key by which the bolt is turned or operated.

The lever end of the bolt B rests or bears upon a spring, C, which prevents it from moving or turning, casually holding it in either a locked or unlocked state. The bolt has a curved slot, b, made in it near its upper end, and the part e, above the slot, forms the bolt proper, which, when the lock is in a locked state, passes through one hole, d, in the striking-plate I), and enters another hole, d'. (See Fig. 1.

The striking-plate is attached to either the lid or to the fixed part of the device or implement, the former usually, and the lock fitted in the other part, and when the bolt is turned back within the lock the end of the part e fills the hole c in the top of the lock-ease iiush with the upper surface of the case.

In Figs. et, 5, and G a modification of theinventieu is shown, the slot I) in the bolt being dispensed with, and a rib, f, at each side used instead. rlhis l'nodification involves the necessity of an oblong slot, g, being made in the top ofthe lock-case, as shown in Fig. 6. The former mode is preferable in those cases where dust and dirt would be liable to enter slot g.

This arrangement forms a very strong, durable, and simple lock, one which will not bc liable to get out of repair, as there is but one part comprising the bolt, and that has but one movement, or a movement in one directionthe are of a circle.

By having thehubs or bosses a at each side of the bolt east or formed with it and fitted in the sides of the lock-case for the bolt to turn upon, and at the same time serve as a recess to receive the key, a very simple and durable arrangement is obtained for the bolt, the latter being incapable oi' being displaced.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The bolt B, with the rib f, constructed as shown in Figs. 4, 5, and 6 of the drawings, and arranged to operate with the oblong slotted plate g, for the purpose herein speciiicd.
